Created attachment 159746 [details] Outlined the panel with a red border Glad to welcome you! Please make the toolbar a little smaller. Its height takes up a lot of space on the document.

There is always a first time to learn something: You can right-click the toolbar and select a more compact style. It works in many KDE applications.
It does not change anything. Small icon mode is enabled by default. The panel is huge.
If you want it more compact, you have the option to hide either icons or text, hide the menu bar, or go to System Settings to choose a more compact window decoration or widget style. Even smaller icons than 16x16 is not possible, but your screenshot looks like they are 22x22 for some reason. Do you use screen scaling? I don’t think there is another way to make the toolbar smaller.
